特别推荐：企业级加密文件系统 ecryptfs （ubuntu 文件夹加密 ，用起来像正常文件夹）｜附加详细使用说明

我想请问一下：出现这种提示实什么意思呢？
allen@Allen-ProBook:~$ sudo mount -t ecryptfs Downloads eTest
Passphrase:
Select cipher:
1) aes: blocksize = 16; min keysize = 16; max keysize = 32 (not loaded)
2) blowfish: blocksize = 16; min keysize = 16; max keysize = 56 (not loaded)
3) des3_ede: blocksize = 8; min keysize = 24; max keysize = 24 (not loaded)
4) cast6: blocksize = 16; min keysize = 16; max keysize = 32 (not loaded)
5) cast5: blocksize = 8; min keysize = 5; max keysize = 16 (not loaded)

变成乱码了。不行吗

附加一点，ecryptfs 的解密层存在于内存，断电后不会留下任何痕迹（内存不足时可能会被写入硬盘交换文件区，通过特殊方法还是可以还原出这个交换区记录过的文件

我不认为会存在这样的问题, 在Linux系统调用里面有一个选项, 不允许内存中的数据swap到磁盘上, 这种选项通常用于操作一些敏感的数据时, 比如存储密码等.
但不了解的一点是如果系统休眠后, 会不会出现这种情况.

perfect. Just let me mark it.

为什么重复mount加密时老是出错，错误信息如下：
Would you like to proceed with the mount (yes/no)? : yes
Would you like to append sig [1014d20ded49c7d8] to
[/root/.ecryptfs/sig-cache.txt]
in order to avoid this warning in the future (yes/no)? : yes
Successfully appended new sig to user sig cache file
mount：文件系统类型错误、选项错误、/media/ubuntu-kylin/204d9a4e-a552-4331-b179-154da97f3f2d/a 有坏超级块，
缺少代码页或助手程序，或其他错误
有些情况下在 syslog 中可以找到一些有用信息- 请尝试
dmesg | tail 这样的命令看看。

这个应该怎么解决呢
